摘要
光源在摄像测量中的重要作用是使需要被观察的图像特征与需要被忽略的图像特征之间产生最大的对比度,从而易于特征的区分,因此要根据测量的要求合理设计光源。本文首先介绍了光源的基本知识,然后阐述了LED的光学特性,最后着重分析了光源设计所要考虑的四个要素。对工程实践有一定的指导意义。
Light source had the important effect which made the needed characters of image farthest be distinguished from the neglected,thus a reasonable design of light source must be made based on the measurement request.This paper firstly gave a presentation of the basic knowledge of light source,then expounded the optical characteristics of LED,finally analyzed the four factors for light source design emphatically.The research has directive significance for practical application at a certain extent.
